Application med July 2, 1914. Serial No. 646,563.

To all whom it may concern Be it known that ll, GEORGE S. POWER, acitizen of the United States, and a resident of Nutley, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Fluid-Moved Valves, of which the following is aspecification.

This invention relates to a iiuid moved valve, and is an improvement ofmy Letters Patent for fluid moved valve, dated July 21st, 1914, numbered1,104,131. The invention is particularly applicable to a cylinder ,witha reciprocating piston. The organization of the invention consists inpart of a valve with a pair of members each of which comprises at leastone conical frustum, the surfaces of which are reverse-d to each other.The valve is impelled by the e'ect of the How of the driving fluidthrough the contracted area between its outer periphery and the walls ofthe chamber in which it reciprocates, in conjunction with an annularfeed cavity for supplying the requisite amount of the driving fluid atthe requisite pressure.

ln the accompanying drawings some of the various forms in which theinvention may be carried out are exemplified.

Figure 1 represents the top plan view ot a cylinder and itsappurtenances with the invention incorporated therewith; Fig. 2 shows asection of Fig. 1 on the line 2, 2 with a part elevation; Fig. 3 is asection of Fig. 2 on the line 3, 3; Fig. 4 represents an end view of anele-ment, Fig. 5 shows a sectional view of a slight modification; Figs.6, 7, 8 and 9 show sectional `views of further modifications.

Va stuiiing box with the gland 35. Bolts 36 connect the cylinder headsand hold them in place on the cylinder 20. A piston 37 1n said cylinderhas extending therefrom the piston rod 38, which extends through thestuffing box and gland 35 in the usual manner. A boss 40 has formedtherewith .the driving fluid supply port 41. A reducer 42 with the lowerend wall 43 having the opening 44 1s in threaded engagement with theboss 40. The opening 44 is formed with the beveled surfaces 44a whichproduce the annular edge 44h. A steam or Huid inlet pipe 45 is inthreaded engagement with the said reducer 42. The reducer 42 enables theuse of a large mlet pipe like 45, to reduce the friction in said plpe toa minimum. At the same time various reducers like 42 may` be employedwhich each have openings 44 of a different size, to suit driving fluidsof did'erent kinds. The beveled surfaces 44a of the opening 44 enablesthe uid which passes therethrough to only come in contact with theannular edge 44b of said opening.

A valve cage or chest is located in the counter-bore 2l of the cylinder,and comprises the end plate 50 and end ring 51.1 A valve seat plate 52with the valve seat 53 abuts against the ring 51, and has formedtherewith the guide sleeve 54 and the ports 55. A similar valve seatplate is indicated at 56 with the valve seat 57, ports 58 and guidesleeve 59. rllhe plate 56 abuts against the end plate 50, and has formedtherewith the slots 60, which latter prevent cushioning of the valve tobe described.

Between the said valve seat plates is located a separator ring 61 withthe central annular cavity 62 and connecting lugs 63. The said ring isshouldered on its outer surfaces as indicated at 64, forming with thevalve seat plates 52 and 56, the annular feed cavities 65 and 66. Avalve is shown with the reversed positioned double conical frustums 7 0and 71. The frustum 7 0 has formed therewith the valve spindle 72, andthe frustum 71 has formed therewith the valve spindle 73. rlFhe outerface of the frustum coacts with the valve seat 53, and the frustum 71coacts with the valve seat 57. Y

To operate the form of the invention described the driving fluid, steamor air, enters the inlet pipe 45, passes through the opening 44, andthence enters the supply port 41. rlhe Huid then enters the annularcavity 62, and fills the feed cavities 65 and 66. When the movingelements are located, as indicated in Fig. 2, the iiuid is fed from thecavity 62, and enters the annular space or contracted area, between theseparator ring on its end adjacent to the head 32 and the inner face ofthe double frustum 71, thereby moving the valve in the 'direction of thearrow A to seat on the valve seat 57. rlhe horizontal components of theimpulses ci the driving fluid as they enter said contracted area impmgeupon the inner face of the double frustum 71 which augments the movementof the valve. The valve principally receives its movements from theeii'ect of the iiow of the liuid through the contracted area between itsouter periphery and the adjacent edge Vof the separator ring. Theimpingement of the iiuid on the inner face of the frustum of the valvewith the eect of the liow of the Huid over its edge forces the valve inthe direction Aof the arrow A.l The object of the frustum shaped valveis to increase the area between said frustum and the separator ring 61as the 'valve moves to its seat. The movements of the valve d0 notdepend upon the compression in the cylinder 20, and which is conclusivefrom a trial of the apparatus. At the same time, a sufficient amount ofthe fiuid has own through the ports 58, and the longitudinal port 22, to-drive the piston 37 in the direction of the said arrow A. When thepiston 37 passes the exhaust port 25 the fluid escapes through thecavity 27 and pipe 28. After the piston 37 has made its strol're -in thedirection of the arrow A, the fluid from the feed cavity 64 enters theannular space between the frustum 70 and the valve seat 53, enabling thefluid to pass through the ports 55. It then enters the cylinder 20 todrive the piston in a direction opposite to the arrow A. When the pistonis located 1n the position 'shown in Fig. 2, the Tiuid escapes from thecylinder by way of the exhaust port 26, cavity 27 and exhaust pipe 28.

Referring to Fig. 5 a modcation 1s shown with the same end plate 50, endring 51 and separator ring 61. A valve seat plate 80 has formedtherewith the valve seat 81, ports 82 and threaded sleeve83. A valveseat plate 88 has formed therewith the valve seat 89, ports 90 andthreaded sleeve 91. A valve with reversed positioned double conicalfrustums 92, 93 coacts with the valve seats 89 and 81. A valve spindle94 is in the threaded engagement with the sleeve 83 and a valve spindle95 is in threaded engagement with the sleeve 91. The valve spindlescarry the valve having the conical frustums 92, 93 the said valve havingsuitable cavities for the spindles 94 and 95.

In Fig. 6 the invention is shown with the end plate 98 having theprojecting lugs 99, an end plate 100, with ports 101 and the central oening 102. A valve plate 103 with a centralpport abuts against the endplate 100. A valve plate 105 with a central port abuts against the lugs99. A separator ring 107 with the feed cavities 108 is located betweenthe valve plates 103 and 105. The said feed cavities tend to direct thedriving iuid in directions at right angles to valve spindle to bedescribed before entering the annular space between the valve to bedescribed and the valve seats with which the valve coacts. A valvespindle 115 is threaded in the plate 98 and has a head 116 that engagesthe opening 102. A valve with the reversed positioned double conicalfrustums 117 and 118 rides on the valve spindle 115. In Fig. 7 the sameelements are shown as described for Fig. 6, excepting that the separatorring 120 has feed cavities 121 and 122 which are formed to feed thedriving liuid in directions perpendicular to the outer faces of thevalve with the reversed positioned double conical frustums 117 and 118.lIn Fig. 8 the invention is shown with an end plate 130 having theprojecting lugs 131, and end plate 132, with the projecting lugs 133 andcentral port 134. A valve plate 135 abuts against the lugs 133, and hasformed therewith the central opening 136 and the curved feed cavity 137.A valve plate 140 abuts against the lugs 131 and as formed therewith thecentral port 141 and the curved feed cavity 142. A separator ring 143 islocated between the valve late's 135 and 140, and has formed therewitthe feed cavities 144 and 145. The cavities 137 and 144 together form apractically circular annular feed cavity, and the cavities 142 and 145form a similar circular annular feed cavity. A valve spindle 148 is inthreaded engagement with the plate 130 and has formed therewith a crowfoot 149 that engages the opening 136. A valve similar to the onedescribed for Fig. 6 rides on the spindle 148. The feed cavitiesdescribed continually contain the outer circumferential edges of saidvalve.

In Fig. 9 the construction of elements of the invention is quite similarto those described fo'r Fig. 8. An end plate similar to 130 not shown isused. A valve plate 153 -has formed therewith the feed cavity 154 andcentral port 155. A valve plate 156 has formed therewith the feed cavity157 and the central port 158. An end plate 159 is shown with the centralport 160. A separator ring 161 with the feed cavities 162 and 163 andcentral port 164 is located between the valve plates. A valve spindle165 similar to 148 supports the valve with the reversed positioneddouble conical frustums 166 and 167.

The modification just described differs from that shown in Fig. 8 inthat the feed cavities are larger and further separated fromthecircumferential edges of the valve.

It will be noted that the'end plate 50, end ring 51, valvel seat plates52, 56 and the separator ring 61 are detachable one from the other, sothat they can easily be cleaned and repaired or replaced, and the samemay be stated for the elements of the modifications of the invention.
